Protein O-GlcNAc transferase.
based on mapping to UniProt O15294
(1) UDP-N-acetyl-alpha-D-glucosamine + [protein]-L-serine = UDP + [protein]-3-O-(N-acetyl-beta-D-glucosaminyl)-L-serine. (2) UDP-N-acetyl-alpha-D-glucosamine + [protein]-L-threonine = UDP + [protein]-3-O-(N-acetyl-beta-D-glucosaminyl)-L-threonine.
-!- Within higher eukaryotes post-translational modification of protein serines/threonines with N-acetylglucosamine (O-GlcNAc) is dynamic, inducible and abundant, regulating many cellular processes by interfering with protein phosphorylation. -!- EC 2.4.1.255 transfers GlcNAc onto substrate proteins and EC 3.2.1.169 cleaves GlcNAc from the modified proteins.
